Add a Testcafe runner

**Is your feature request related to a problem? Please describe.**
We use [Testcafe](https://testcafe.io) as the E2E test framework for our plateform, but as many other frameworks, it requires a lot of code (and so, dev time) to create a new test. UUV would allow us to have clearer and simpler tests scenarii

**Describe the solution you'd like**
I would like to be able to integrate UUV to our existing tests suite, hence having a way to have UUV and testcafe to work together

**Describe alternatives you've considered**

**Additional context**

Start by reviewing UUV's existing test-runner integrations and the current tests, then compare them with the Testcafe test suite described in the issue. Done means UUV can work with an existing Testcafe suite, but the issue does not identify specific files, entry points, or acceptance tests.
